Purpose of Unit

The purpose of this unit is to get the students thinking about how humans impact their environment. At this point in their education, students probably have been exposed to some ecological concepts and have a basic understanding of ecosystems and how they function. The concept of equilibrium in ecosystems will be investigated as students examine ecosystems as open systems

Students will then investigate the Narragansett Bay Ecosystem and its different habitats and research how the human population has impacted it over time. Topics that will be investigated will be invasive/introduced species, overpopulation, habitat destruction, pollution, and the impact of global warming on the bay. Students will then take a look at how the balance of ecosystems can be disrupted and students will begin to to investigate their roles as organisms in an ecosystem.

From this unit students should gain an understanding of ecosystems as open systems that can be influenced by external factors. Students will examining how the human population impacts the stability of ecosystems as well as examining their own individual impact on ecosystems, their ecological footprint. The goal of this unit is to make students more ecologically aware of there surrounding and their connection and impact on the biosphere.
